Description : what do not change in transformer?

Answer : Frequency and power are constant in transformers. Suppose we apply 50 Hz input frequency then the output frequency will also be 50 Hz whether the transformer is step up or step down. Similar ... is decreased on secondary side and hence power on primary side and secondary side remains constant.

Answer : If the supply frequency to the transformer is increased, the iron loss will increase.
